Logbook Diary starting on July 28, 1955 from Redding to East Coast. Notes indicate Alice and Marve were on trip with Earl & Mary; there is no mention of Margaret.
I added maps along the trip totaling 3165 miles from Melrose Park (3590 from Redding). Vehicle got 13 mi/gallon. Near end of logbook, it looks like phone numbers (Naomi) and game.
